IronCad	Beyond existing production solid modeling, IronCAD advances windows based mechanical engineering into the realm of productivesolid modeling. A radical new drag and drop 3D environment and an advanced visual approach makes anyone fast and effective in creating and modifying designs. IronCAD's unique architecture and patented technologies enable all collaborators to confidently share in a concurrent design process without regard to who built the model, how it was created, or which CAD system was used.
Mechanical Desktop	With Mechanical Desktop software you can perform virtually all the 2D and 3D design, analysis, and manufacturing tasks required for production from a single environment, faster and less expensively than with most other systems. It provides all the functionality of AutoCAD 2000 software with more than 400 new or enhanced features. Integrated within this platform are dozens of powerful, timesaving mechanical design and engineering features including Genius Desktop 3 capabilities and the 2D drafting toolset of AutoCAD Mechanical Release 14.5. And the ACIS 5 kernel means you can model more-complex geometry, faster than ever.
Microstation	MicroStation Modeler combines leading-edge technology with broad, stable functionality, letting you excel in each stage of the engineering life cycle. Enhancing your ability to create and communicate your designs, enabling you to share and manage engineering data more easily across your entire enterprise, empowering you with a single engineering model for design, analysis and manufacturing.
Rhinoceros	Rhinoceros can create, edit, analyze, and translate NURBS curves, surfaces, and solids in Windows. Rhino has limited support for polygon meshes. There are no limits on complexity, degree, or size. extremely fast 3-D graphics, unlimited viewports, working perspective views, coordinate read-out, named views, named construction planes, customizable icons and user workspace...Rhino was designed to run on ordinary Windows desktop and laptop computers and no special graphics cards are required.
Solid Concept	Solid Concept is 'professional level, variational para-metric solids CAD/ CAM software' at its best. It includes in a single environment all the tools needed for conceptualizing, designing, drafting and machining. True "Art to Part" productivity in one cost effective package. Solid Concept is the first professional level CAD/ CAM package to offer high-end features at a price that is more generally associated with 2D CAD packages.
SolidEdge	Solid Edge, Unigraphics Solutions' mid-range CAD software package, provides breakthrough performance for mechanical assembly design and drafting, combining production-proven solid modeling and unparalleled ease of use at an affordable price. Stream technology optimizes overall workflow efficiency by improving the speed and effectiveness of user interactions. Stream technology is why more people learn to use Solid Edge on their own, with little or no classroom training. It’s why designers, engineers, and drafters are so comfortable and productive with powerful features that are easy to master and control.
SolidWorks	SolidWorks is the standard in 3D product design mechanical design software for Windows. Its unique combination of production-level power, ease-of-use and affordability is unmatched. SolidWorks automates the process of capturing and modifying design intent, enabling you to move through the design cycle in record time. SolidWorks offers user interface improvements as well as significant new file translation, detailing, assembly design, part modeling, and built-in migration tools that ease the move from 2D to 3D. SolidWorks enhances the productivity of all mechanical engineers and designers, regardless of previous CAD experience.
